Abstract

The invention concerns an element of a screw compressor injected with water containing two rotors (2-3) in a rotor chamber (4). The water circuit (11) contains a part (10) in which practically prevails the outlet pressure. On the inlet side, the axle journals (13, 16) are radially supported on hydrodynamic slide bearings (18, 19). In the housing (1) opposite to the crosscut ends of the axle journals (13, 16) are formed chambers (20, 21) which are connected to the above-mentioned part (10) or to the inside of the rotor chamber (4). On the outlet side, the axle journals (14, 17) are radially supported on hydrodynamic slide bearings (25, 26) on the one hand, and they are axially supported on hydrostatic slide bearings (27, 28) on the other hand which are connected to the above-mentioned part (10) of the water circuit (11), or on hydrodynamic slide bearings (37, 38).
